Erin Goode MS 110 Section 004 April 1, 2010 Homework #1- Review of the Article Is Creatine Worth the Weight? 1. Creatine is a non-essential nature compound that is found in the body. Also, athletes commonly use creatine as a dietary supplement. Creatine is found primarily in the body’s skeletal system where it works as an energy buffer. Creatine can be found in free or phosphorylated forms, as phosphocreatine. Phosphocreatine (PCr) donates a phosphate to ADP to create ATP during times when muscles are at high-energy demand. This ATP-PCr system is the only muscle system that produces enough energy to complete these tasks of extreme effort, but the maximum amount of ATP only lasts for a brief time before the store of PCr begins to deplete. 2. Evidence form the article has shown that creatine supplementation can improve athletic performance because people that ingest creatine have a larger energy reserve available to create ATP when doing energy demanding activities. After a creatine load, athletes have 25% their maximum muscle level, allowing them to begin their workout with more muscle creatine available to produce energy. Using creatine supplementation has the same effects on an athlete as carbohydrate loading before a competition. Some people that use creatine supplements may have more than a 30% increase in their creatine amount. Hundreds of studies have
